а) $\frac{8}{9} : 6$;
б) $15 * \frac{5}{6}$;
в) $1 : \frac{3}{7}$;
г) $\frac{2}{5} * 12$;
д) $2\frac{7}{9} * 15$;
е) $3\frac{1}{3} : 30$.
$\frac{8}{9} : 6 = \frac{8}{9} * \frac{1}{6} = \frac{4}{9} * \frac{1}{3} = \frac{4}{27}$
$15 * \frac{5}{6} = 5 * \frac{5}{2} = \frac{25}{2} = 12\frac{1}{2}$
$1 : \frac{3}{7} = 1 * \frac{7}{3} = 2\frac{1}{3}$
$\frac{2}{5} * 12 = \frac{24}{5} = 4\frac{4}{5}$
$2\frac{7}{9} * 15 = \frac{25}{9} * 15 = \frac{25}{3} * 5 = \frac{125}{3} = 41\frac{2}{3}$
$3\frac{1}{3} : 30 = \frac{10}{3} * \frac{1}{30} = \frac{1}{3} * \frac{1}{3} = \frac{1}{9}$
